UK : Telesoft Technologies announced the ability to monitor the access network IP interfaces in CDMA2000 EV-DO mobile networks, an enhancement to its CDMA monitoring capabilities. Passively monitoring a CDMA2000 mobile network allows service providers to manage the network and OEMs to offer value added services to customers including location based and roaming services.

In 3G configurations, CDMA2000 EV-DO uses data packets rather than dedicated circuits in the access network. Passively monitoring and extracting signalling and data information in packet networks however is doubly difficult as the packets are multiplexed together during transmission.

“Packet based technology is being used in 3G networks worldwide to vastly reduce infrastructure costs and support next generation subscriber services”, said Ray Hutton, Product Manager, Telesoft Technologies. “Our customers are demanding a CDMA2000 EV-DO packet monitoring capability enabling them to offer value added services such as location based advertising and welcome messages as well as services such as lawful interception which rely on monitoring probes to analyse signalling and gather user data”.

The interfaces monitored are the A1(P), A2(P) and A5 interfaces which carry the signalling and user data between the Access Network Controller (ANC) and the Mobile Switching Centre (MSC) on copper or optical fibre links . Countries with CDMA2000 networks include: USA, South Africa, India, Brazil and Japan. Europe and much of the rest of the world uses the UMTS 3G standard, monitoring of which is also supported by Telesoft Technologies.
